Answer: 80 students
Answer:
|-15| > |-5|
-15 < -5
Step-by-step explanation:
|-15| ○ |-5|
Absolute value means take the positive value
15 ○ 5
15 is greater than 5
15 > 5
-15 ○ -5
negative 15 is less than -5
-15 < -5
We'll get started on that as soon as you share the whole
table of other information that goes with that question.
Let:
Larger number = x
Smaller number = y
-------------------------------------------------------------------------------------------------------------------
x + y = 49
x - y = 21
-------------------------------------------------------------------------------------------------------------------
Isolate the x in the first equation. Subtract y from both sides
x + y (-y) = 49 (-y)
x = 49 - y
-------------------------------------------------------------------------------------------------------------------
Now that we know what x is, plug in 49 - y (which = x) into x in the other equation.
x - y = 21
(49 - y) -y = 21
Simplify.
49 -2y = 21
Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First subtract 49 from both sides
-2y +49 (-49) = 21 (-49)
-2y = 21 - 49
-2y = -28
Next, divide -2 from both sides to isolate the y
-2y/-2 = -28/-2
y = -28/-2
y = 14
-------------------------------------------------------------------------------------------------------------------
Now that we know what y is, plug into one of the equations.
x + y = 49
x + (14) = 49
Isolate the x. Subtract 14 from both sides
x + 14 (-14) = 49 (-14)
x = 49 (-14)
Simplify
x = 35
-------------------------------------------------------------------------------------------------------------------
Answer:
Larger number: 35
Smaller number: 14
-------------------------------------------------------------------------------------------------------------------
